ROTARY. METER.

SPECIFICATION forming part of Letters Patent No. 271,233, dated January30, 1883,

Application filed September 16, 1882. (No model.)

To all whom it may concern:

Be it known that I. HENRY FREDRIGK, a

citizen of the United States, residing at Newexact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being bad to theaccompanying drawings, and to letters of reference marked thereon, whichform a part of this specification.

The object of this invention is to reduce the cost of construction andfacilitate and improve the operation of water-meters, and to measure thewater with greater correctness than by means of those heretoforeemployed.

The invention consists in the arrangement and combination of parts,substantially as will be hereinafter set forth, and finally embodied inthe claims.

Referring to the accompanying drawings, in which similar letters ofreference indicate like parts in each of the several figures, Figure 1isas'ectional viewof myim proved meter, showing the internalarrangements of the parts. Fig.2 is a plan of a dial for indicating thequantities of water passed the meter, showing the arrangement of a trainof cogs, whereby the pointers above the said dial-plate are actuated toindicate said quantities. Fig. 3 is a detached sectional plan of rotating arm s, ada p t ed to be caused to revolve under theintluence of thewater, which arms actuate the severalparts hereinafter mentioned.

In said drawings, ct represents a box having an inlet-port, b, andexit-ports c 0, also threaded side walls to receive a diaphragm, d, anda cap, 6. Said diaphragm divides or separates the box a into anupperandlower chamher, the latter receiving and discharging the waterthrough the ports. The upper chamber is separated from the lower sothoroughly as that no water can enter, as will be hereinafter describedbut should a leak occur because of wear or imperfect workmanship theupper chamber, receiving such leakage, and being thoroughly disconnectedfrom theindicatingmechanism containing chamber it, prevents the accessof water to said mechanism. Said inlet-port has or may have threadedside Walls, and into the same is secured an upwardlyprojecting tubularportion, f, having side ports therein, and having its upper extremityclosed byacap,g. Said projecting portionfreceives the rotating arms t.the former acting as a pivot for the latter. The hub h, or connectingportion of the arm, is provided with a cap, 6, having a central aperturetherein, in which latter a rod,j, has a lower bearing. The connectedarms t from their peculiar shape, hereinafter described, cause the rod jto revolve therewith, as will be apparent from the draw- .ings, the capi being rigid in its relation to the hub, and the bearing extremity ofthe rod being angular or otherwise formed, whereby said action isperformed. The rod 9' passes upward through the diaphragm d, as shown inFig. 1, a water-tightjoint being formed at this point by means of thebox It, secured upon the said rot and revolving therewith, covering aprotuberance on the diaphragm, the parts being ground together toproduce said joint. A similar jointisformed wheretherod passes throughthe cap 0 of the water-meter, a second cap, m, being. formed to engagewith a projecting head. From the meter-box a the rod j passes upwardinto a second box, at, having a train of cogwheels and other mechanismarranged therein, whereby the amount of water passing through the meteris measured. Said mechanism and cogs may be arranged in any appropriatemanner to produce the result, the simplest method being, however, asfollows: The upper end of the rod is provided with a screw-thread, asshown in Fig. 1, which thread engages with a small cog, p, Fig. 2,carried by the shaft 9. Said shaft is provided with threads, whichengage with and actuate the train of cogs with their pinious r r r r W.The cogs are-connected with and actuate the pointers .9 upon the face ofthe dial, which latter is provided with graduated scales, (not shown,)by which the quantities of water are indicated. The arms tare curved andtubular, as shown, and receive the water through the side opeuiugsin thetubular portion f. The greater the quantity of water passing through thearms the greater will be the rotary speed of the same, as will beapparent.

Having thus described my invention, what I claim, and Wish to secure byLetters Patent, is- 1. In combination. in a water-meter, the box at,having the diaphragm d and cape, the tubular portion f projecting intothe said box, having opening therein, the curved tubular arms working onsaid projecting portions f, the rodj, actuated by the arms, andconnecting the latter with the indicating mechanism, arranged in the boxn, secured to the cover 6, all said parts being arranged and operatingsubstantially as set forth and shown.

, box a, all said parts being arranged and operating substantially asset forth and shown.

In testimony that I claim the foregoing I have hereunto set my hand this13th day of September, 1882.

HENRY FREDRIOK.
